Antimonite

In chemistry, an antimonite refers to salts of antimony(III), such as NaSb(OH)4 and NaSbO2 (metaantimonite) which can be prepared by reacting alkali with antimony trioxide, Sb2O3.[1] These are formally salts of antimonous acid (antimonious acid[2]), "hc(OH)3" whose existence in solution is dubious, and attempts to isolate it generally form Sb2O3·xH2O, antimony(III) oxide hydrate, which slowly transforms into Sb2O3.[1]

In geology, the mineral stibnite, Sb2S3, is sometimas called antimonite.


They can be compared to antimonates, which contain antimony in the +5 oxidation state.
